High Performance, 4-20mA Output Voltage-to-Current Converter
2B20
FEATURES Complete, External Components Needed Small Size: 0.4" Module Input: +10V; Output: 20mA Drift: 0.005%/°C max; Nonlinearity: 0.005% (2B20B) Wide Temperature Range: -25°C +85°C Single Supply: +10V +32V Meets 50.1 Type Class Nonisolated Current Loop Transmitters Economical APPLICATIONS Industrial Instrumentation Control Systems Converter Current Loop Interface Analog Transmitters Controllers Remote Data Acquisition Systems
GENERAL DESCRIPTION Model 2B20 complete, modular voltage-to-current converter providing user with convenient produce current output signal which proportional voltage input. nominal input voltage range +10V. output current range 20mA into grounded load. Featuring drift (0.005%/°C max, 2B20B) over -25°C +85°C temperature range single supply operation (+10V +32V), model 2B20 available accuracy grades. 2B20B offers precision performance with nonlinearity error 0.005% (max) guaranteed offset error ±0.1% span error ±0.2% max, without external trims. 2B20A economical solution applications with lesser accuracy requirements, featuring nonlinearity error 0.025% (max), offset error ±0.4% (max), span error ±0.6% (max), span stability 0.01%/°C max. 2B20 contained small (1.1" 1.1" 0.4"), rugged, epoxy encapsulated package. maximum versatility, signal input (VIN1 VIN2) reference input (REFIN1 REFIN2) terminals provided. Utilizing terminals VIN1 REFIN1 eliminates need external components, since offset span internally calibrated. higher accuracy ±0.01%) required, inputs VIN2 REFIN2 with series trim potentiometers utilized. APPLICATIONS Model 2B20 been designed applications process control monitoring systems transmit information between subsystems separated system elements. 2B20 serve transmission link between such elements process control system
transmitters, indicators, controllers, recorders, computers, actuators signal conditioners. typical application, model 2B20 interface between converter output microcomputer-based system process control device such variable position valve. Another typical application 2B20 current output stage proportional controller interface devices such current-to-position converters current-to-pneumatic transducers. DESIGN FEATURES USER BENEFITS Process Signal Compatibility: provide output signal compatibility, 2B20 meets requirements Instrument Society America Standard S50.1, "Compatibility Analog Signals Electronic Industrial Process Instruments" Type Class nonisolated current loop transmitters. External Reference Use: increased flexibility, when ratiometric operation desired, 2B20 offers capability connecting external reference (i.e., from multiplying converter) REFIN2 terminal. Wide Power Supply Range: wide power supply range (+10V +32V allows operation with either +12V battery, +15V powered data acquisition system, +24V powered process control instrumentation.
